【摘要】 助复剂的选择与配制是小变形条件下采用扩散-轧制法生产复合钢板的关键问题之一.为了开发一种适用于碳钢,并在低中温(<850℃)条件下使用的助复剂,研制了一种以铜为基体元素,锌为主要合金元素,锰为主要添加元素,再加入少量的硅、锡、镍、微量的硼和稀土的助复剂,对其成分配比进行了设计并在冶炼过程中对钢板进行了涂镀.扫描电镜及轧制结果表明,助复剂与钢板接合处发生了原子之间的扩散,界面结合较好,助复剂厚度达到后续小变形轧制复合的要求.更多还原

【Abstract】 In order to produce diffusion-rolling sandwich panels under small reduction, a bonding assistant coat which mainly contains Cu, Zn, Mn and small amount of Si, Sn, Ni, B and rare earth elements was designed for carbon steel plates at 850℃. The results of SEM and rolling showed that atom diffusion between the carbon steel plate and the bonding assistant coat took place, the interface combination was satisfied and the thickness of bonding assistant coat accorded with small reduction later.更多还原
